History tells us more than we want to know about what is wrong with man, and we can hardly turn a page in the daily press without learning the specific time, place, and name of evil. But perhaps the most pervasive evil of all rarely appears in the news. This evil, the waste of human potential, is particularly painful to recognize for it strikes our parents and children, our friends and brothers, ourselves.

In terms of the game theory, we might say the universe is so constituted as to maximize play. The best games are not those in which all goes smoothly and steadily toward a certain conclusion, but those in which the outcome is always in doubt. Similarly, the geometry of life is designed to keep us at the point of maximum tension between certainty and uncertainty, order and chaos. Every important call is a close one. We survive and evolve by the skin of our teeth. We really wouldn't want it any other way.

The simplest single-celled organism oscillates to a number of different frequencies, at the atomic, molecular, sub-cellular, and cellular levels. Microscopic movies of these organisms are striking for the ceaseless, rhythmic pulsation that is revealed. In an organism as complex as a human being, the frequencies of oscillation and the interactions between those frequencies are multitudinous.
